<para>
Converts the BSON document to its
<link xlink:href="&url.mongodb.specs.extendedjson;#canonical-extended-json-example">Canonical Extended JSON</link>
representation. The canonical format prefers type fidelity at the expense of
concise output and is most suited for producing output that can be converted
back to BSON without any loss of type information (e.g. numeric types will
remain differentiated).
